There are quite plausible reasons for opposing views because athletic is not an imperative subject at school, so it is not necessary to become a subject. In their other opinions, if someone interested in physical activity, they just come to gymnasiums or squares from the outside and practice it. However, I feel some advantages when students play sports in school. There are three primary reasons for this.

First of all, sports ensure the body of students will healthy. Every week, the school children have a period time to play sports, which will support their body strongly and actively. When they play often, not only good for health, but also help the passive students adapt to their environment actively, and cause them more alive in society.

Secondly, sports create the unity between individual and the others. By playing sports, students will easy to make friends, sociable with class their and improve their leadership. From many skills above, they work comfortably in groups, easily share ideas to each other. Thus, their studying will be better and grow up comprehensively, which are results of effective education.

Finally, sports promote talented students themselves and orientate them into better way in their future. For example, if you were good at playing soccer, you should try to become to a national players. You will bring pride to your country and your own too.

By way of conclusion, I once again reaffirm my position that athletic is very important to every student. Given the significance of sports with this my opinion, I believe that everybody who think it is no need will have positive thoughts about physical activities.

First of all, sports ensure the body (bodies) of students will healthy (healthy là tính từ, cần 1 tobe để bổ sung). Every week, the school children have a period time to play sports (should spend some times playing sports), which will support (back up = sponsor = subsidise = finance) their body( bodies) strongly and actively ( chỉ dùng trạng từ khi nó bổ sung cho động từ chính, ở đây strong và active bổ sung cho body chứ k phải support, vì vậy cậu nên chuyển câu này thành "which will help their bodies stronger and more active" ) . When they play often (often play, tiếng Anh thường ngược lại tiếng Việt, chơi thường xuyên => thường xuyên chơi) , not only good for health, ( thiếu chủ ngữ cho câu) but also help the passive students adapt to their environment actively, and cause them more( tối nghĩa cậu ạ ) alive in society.

Secondly (Should be "moreover), sports create the unity between individual and the others. By playing sports, students will easy to make friends (will make friends easily) , sociable ( sociable k là động từ) with class their (their class) and improve their leadership ( ở đây ko có điều gì khiến improve leadership cả). From many skills above, they work comfortably in groups, easily share ideas to each other. Thus, their studying will be better and grow up comprehensively, which are results of effective education.

Finally, sports promote talented students themselves and orientate them into better way (foster them to have a better future) in their future (futures). For example, if you were good at playing soccer, you should try to become to a national players.( a đi với danh từ số ít nhé cậu: a national player) You will bring pride to your country and your own too.

By way of conclusion, (too complicated, "In conclusion" I once again reaffirm my position that athletic is very important (vital, crucial) to every student. Given the significance of sports with this my opinion, I believe that everybody who think it is no need will have positive thoughts about physical activities.
